No ECLK—Disable ECLK output
This bit controls the availability of a free-running clock on the ECLK pin. This clock has a fixed rate equivalent to the
internal bus clock.
1 ECLK disabled
0 ECLK enabled
No ECLKX2—Disable ECLKX2 output
This bit controls the availability of a free-running clock on the ECLKX2 pin. This clock has a fixed rate of twice the
internal bus clock.
1 ECLKX2 disabled
0 ECLKX2 enabled
Free-running ECLK predivider—Divide by 16
This bit enables a divide-by-16 stage on the selected EDIV rate.
1 Divider enabled: ECLK rate = EDIV rate divided by 16
0 Divider disabled: ECLK rate = EDIV rate
Free-running ECLK Divider—Configure ECLK rate
These bits determine the rate of the free-running clock on the ECLK pin.
00000 ECLK rate = bus clock rate
00001 ECLK rate = bus clock rate divided by 2
00010 ECLK rate = bus clock rate divided by 3, ...
11111 ECLK rate = bus clock rate divided by 32
